- 3 Claims. c1. 4-252) This invention relates to plumbing fittings and more particula ly to an improved means for connecting tollets and other floor mounted fittings and articles to a soil.

p In building construction, the soil pipes are installed before the building is erected and the ends thereof to which toilets, urinals, floor drains and the like are after wards to be connected are placed to terminate above the floor line. This is known as roughing in the plumbing. Where the floor is to be concrete, the rings to which the toilets or other fixtures are to be secured are placed on the pipes with their upper surface located at the floor line and are held in that position by any suitable means such as Wedges inserted between the ring and the pipe. These rings are provided with oppositely disposed slots in which the hold down bolts for the toilet or other fixture to be attached are to be inserted and incident to pouring of the fioor these slots and the necessary clearance space beneath them are filled with concrete which must then be laboriously chipped away by the plumber in making the connection to the ring. Incident to that operation the space between the ring and the pipe is filled with a lead caulking to seal the joint and to secure the ring to the soil pipe and the excess soil pipe is cut or broken away to the level of the upper surface of the ring.

The present invention, taking into account these laborious steps, has for one of its objects the provision of an improved ring for attachment of fioor mounted plumbing fixtures to a soil pipe characterized by having means for attaching it to the soil pipe prior to the formation of the floor at the desired height and in a. level position regardless of any departure of the soil pipe from the vertioal.

Another object of the invention is the provision of an improved hold down bolting means for attaching toilets and the like to the soil pipe ring which is so constructed and arranged as to be mountable on the ring prior to the pouring of the floor with resultant securing of the ring attached portion of the bolting means in the floor and the elimination of the time heretofore required to chip away the concrete to form clearance for the bolting means.

A further object of the invention is to provide an improved floor connection between a .soil pipe and a plumbing appliance to be connected thereto.

With the foregoing objects in view, together with such other obiects and advantages as may subsequently appear, the invention resides in the parts, and in the construction, combination and arrangement of parts, described by way of example in the following specification of one mode of execution of the invention; reference being had to the accompanying drawings which form a part of .raid specification and in which drawings:

Fig. l is a side elevation of the invention employed in making the soil pipe connection for a toilet,

Fig. 2 is an exploded View of the component parts of v the form of the invention shown in Fig. 1 employed in making the said connection,

Fig. 3 is an enlarged transverse fragmentary sectional view taken on the line 77 of Fig. 1 showing the first step in making the connection,

Figs. 4,5 and 6 are views similar to Fig. 3 but showing successive following steps in making the connection, and

Fig. 7 is a full section taken on the line 77 of Fig. 1 in a reduced scale as compared with Figs. 3, 4, 5 and 6, showing the completed connection or joint.

The principal parts of the invention are shown in Fig. 2 and comprise a ring 1 preferably formed of cast iron generally similar in length, diameter and configuration to a standard so-called toilet ring heretofore used for connecting a toilet to a soil pipe, together with certain other elements to be presently described.

The ring has a stepped internal surface comprising a smaller diameter lower portion 2 and a larger diame-v ter upper portion 3 corresponding in internal diameter and length to the internal diameter and length of the bell portion of the size of soil pipe with which the ring is .to be used. The lower portion 2 fits loosely over the exterior surface of the soil pipe P and is clamped thereto by means 'of three set screws 4 threaded through the walls of the said lower portion and engaging the soil pipe. The ring is thus secured to the soil pipe end with the upper end flush with the plane of the floor of the building and by suitable adjustment of the set screws 4 the bolting flange 5 of the ring can be positioned leveled in the floor plane.

The flange 5 is provided with diametrically opposite holes 6, 6 in which either prior to the initial attachment of the ring to the pipe or immediately thereafter,

are located the shank portions 7, 7 of nuts 8, 8 clamped to the under face of the flange by screws 9, 9 threadedly engaging the threaded holes 10, 10 of the nuts; said screws preferably having wide flanged heads 11, 11 en gaging the upper surface of the ring and having shallow the nuts 8 thus securing them permanently in position.'

The threaded holes 10 in the nuts do not go through the nuts and the screws 9 close the open ends of the:

holes so that upon removal of the screws, the holes are clean and ready for reception of the hold down bolting means as will be later described in more detail. Preferably, these nuts as well as the fixture securing bolts or studs are formed of non-ferrous metal. Additionally, the flat heads of the screws 9 otter no opposition to the tools employed in smoothing the floor. 3 1 After the flooring material has set, the operations 0 further completing the joint may be resumed; At that' time, the parts are as shown in Fig. 4. Preferably, but not necessarily, the inner periphery of the ring isprovided with a shallow peripheral groove 13 at the shoulder 14. formed by the juncture of the inner diameter surfaces 2 and 3 and a thin, resilient collar or washer 15 having: the inner periphery slitted to form'a series of narrow: tongues 16 is pressed down into the space between the: larger diameter portion 3 of the ring and the outer sura, face of the soil pipe and is seated on the shoulder .14 with the outer periphery of the washer tightly engaging the inner wall of the ring ,atthe bottom of the groove 13;

The washer maybe formed of heat resistant paper or vulcanized fiber, or if such washer is not available, the space between the inner surface 2 of the ring and the a suitable plastic or putty type of material.

Thus positioned, as shown in including the groove 13, is then caulked by filling with asuitable caulking material, molten lead beingthat most commonly used, as shown in Fig. at 17; the projection of the caulking material into the groove 13 providing additional. anchorage for the caulking in the ring. The only function of the washer 15- or the equivaient plastic material is to serve as a dam to retain the lead in this space when it is still molten.

When the lead has hardened, any projection of the soil pipe above the level of the flange Sis cut or broken away and the screws 9,9 are removed leaving the end of the soil pipe connection thus formed ready for connection of a toilet as shown in Fig. 6.

The finished joint is shown at Fig. 7 in which a toilet T is positioned with the outlet 0 thereof inside the bell end of the ring 1 and with the bolting flanges F thereof provided with a depending rib R which engages the upper surface of a gasket G lying on the upper face of the flange 5. The bolting means comprises threaded stud 18, 18 each having one end thereof threadedly seated in the nuts 9, 9 and extending upwardly there from through holes H in the toilet flange F and carrying nuts 19, 19 and washers 20, 20 bearing against the flange F and bolting itv securely against the gasket G to complete the connection. Additionally, in the case of toilets and some other fixtures, additional bolts B are employed to secure the fixture to the floor; such bolts having no effect in the formation with the joint with which the present invention is concerned.

While the invention has been described in detail in connection with the installation of a toilet, it will be apparent that it is not limited to this specific use and that for the installation of other fixtures such as floor type urinals, floor drains, and the like, other rings having differently arranged and spaced holes in the bolting flanges thereof may be employed to suit the particular type of fixture to be connected to the soil pipe thereby. Also, while the invention has been disclosed as applied to installation in connection with a concrete floor, it will be obvious that the adjusting set screws are equally valuable in setting the ring in position where the floor is to be of wood or any other material and that when the point is caulked by the pouring of lead, the ring is securely anchored to the soil pipe thereby. Further, the novel anchoring nut means may be employed with the rings in current use by being placed in the slots used in such rings for insertion of the bolts heretofore used. With these considerations in mind the invention is not to be deemed to be limited to the specific form thereof above described by way of example, and it is to be understood that the invention embraces all such changes and modifications in the parts and in the construction, combi-. nation and arrangement of parts as shall come within the purview of the appended claims.
